Fall asleep to the sound you actually want, and get back to sleep when you wake at 3 a.m.

Sleep Deep is a sleep sounds app built around a mixer. Layer real recordings of rain, ocean surf, a river, a campfire and a box fan with brown, pink or white noise, quiet music and a slow, calm voice. Set every level yourself, save the mix, and start it with one tap. Free to start, no account needed.

MIX YOUR OWN SLEEP SOUND
• 27 long recorded nature and ambient sounds: rain on a window or tent, distant storm, surf, stream, wind, crickets, frogs, owls, a wood stove and more
• Brown, pink and white noise, generated live so they keep changing as they play
• Layer up to five sounds and set each volume
• Save mixes by name, and start them from a widget or the Quick Settings tile

SLEEP MUSIC AND VOICE
• Five slow, soft music pieces for harp, flute, strings and piano. Set the pace, the room and each instrument
• Low hum, slow pulse and binaural beat tones (the beats need headphones)
• Wind-down voice sessions that play over your mix or on their own, then hand the night back to the sound
• A short breathing exercise before bed

BUILT FOR THE MIDDLE OF THE NIGHT
• Sleep screen: true black with a dim ember glow and a soft clock. No blue light, nothing to read
• Night arc: your sound fades gently as you drift off instead of cutting out, and can rise softly to wake you
• Back to sleep: woke up at night? One tap starts a quiet session to help you drift off again
• Choose how Stop works: one tap, tap twice, or press and hold
• Bedside clock mode in landscape

WORKS OFFLINE
Everything is bundled with the app. It plays in airplane mode withcan you ge nothing to download, and keeps playing with the screen off.

A GENTLE MORNING
One question when you wake: how did you sleep? Your nights are kept in Settings.
